Drive an older car that doesn’t come equipped with electronic locks? We’ve been there, so we know all too well how easy it can be to manually lock everything up, slam the doors, and then realize that you accidentally left your keys RIGHT on the front seat!

If you find yourself in this aggravating scenario, don’t call a pricey locksmith when you can release your locked door by threading a couple of meters of ordinary string through the lock. Protip: If you’ve managed to lock your string in the car as well, just tie together your shoelaces!

While today’s sleek dashboards and consoles may look a heck of a lot sportier than the clunkier interiors seen in most older cars, they are missing one key feature—storage space! Luckily, your average dollar store toothbrush holder serves as a perfect storage device for small items like pens, cosmetics, or coins.

Stick it in your cup holder, or hide it in your concealed storage console; you’ll be amazed at how that one, simple change can free up so much space!

Give the floating items that live in your car’s trunk (i.e. sunscreen, diapers, extra clothing, first aid kit, etc.), a permanent place in a plastic storage bin. Not only is this hack super economical, it will only take you a few minutes to organize the items into their new home.

Don’t get caught spraying noxious chemicals on your dusty interior when a couple of drops of all-natural olive oil does the job just as well. Just wipe away with a microfiber cloth and you are good to go!

Did you know that the items that you use to keep your mouth clean are the same ones that can restore your old headlights? A good brushing will not only make your car look ‘younger’, it will also ensure that your lights shine as bright as possible.

If you feel like you are constantly fighting a losing battle against foggy windows, look no further than this ingenious cat litter pouch. ‘Why cat litter?’ you may be asking? Well, it turns out that the handy item does a great job at soaking up excess moisture in the air. It may sound weird, but it works!

Believe it or not, balled up dryer lint works wonders on the most stubborn of ‘bird droppings’. Just stick a drying cycle’s worth in a plastic baggie and break out the lint whenever you notice one of those annoying white stains. It works wonders and it WON’T scratch your paint. Score!

It’s safe to say that we all have fears of getting stuck on the side of a deserted road with a dead car battery. Talk about scary! Luckily, there is a tried and true hack that, with a bit of elbow grease, has been known to revive batteries. All you need is a jack, a rope, and a little bit of strength!

Nope, it’s not about hydration; traveling with a filled water bottle means you could also be reaping the benefits of a stronger cell signal when you need it. Just place the bottle of water by your device, restart if necessary, and instantly enjoy more clear calls and faster searching. Who knew?!

Let’s be honest; there’s nothing worse than getting your new car’s doors scratched or bumped in a parking lot, but luckily, there’s a preventative measure that you can take. You wouldn’t believe it, but attaching halved pool noodles to the exterior bolt heads will create a protective barrier between you and the other car. It may look a bit silly, but the hack sure does work!

If you live in a freezing cold climate, then you should really make rubbing alcohol your new best friend this winter! Not only is the stuff dirt cheap, it is also known to dissolve frost on windshields fast. Just mix with some water, spray on, and watch the magic happen.

Years of nasty weather can really do a job on your windshield, making visibility challenging, especially at night. Fortunately, getting your glass back to factory-fresh is a simple process—and it starts with cleaning that window with steel wool, of all things. Who would’ve thought?!

We don’t know about you, but we are literally throwing all of these items in our trunk as we write this. Talk about handy!
